Was told u could mess up the electrical system if the r134a was used
Do you have to use a special freon and guages/hose due to it being a hybrid on 2007 Nissan Altima Hybrid
IF the A/C compressor is belt driven AND electrically run (when gasoline engine is stopped) then YES you DO need a Different kind of OIL for the system , although the refrigerant is still R-134. NO BULL .........best bet-check with dealer/Nissan tech ,before making the wrong (and possibly very expensive) mistake.
Bull, your car take R134a freon, good luck.
